I've had them for a good while now and I drive a LOT. (>23k in 13 months)
Zero issues or CELs. They have that no-cat smell and they're raspy with the stock (Nismo) exhaust. Without a tune I've noticed a little lag below 3K RPM and occasional lulls depending on throttle position during acceleration. I'm very happy with my purchase and trust me, you will feel the difference.
